Abstract
This invention relates to the use of a water-soluble or water-dispersible copolymer comprising, in the form of polymerized units of at least one monomer compound bearing a quaternary ammonium (a) and at least one hydrophilic monomer (b) bearing a function of acidic nature which is copolymerizable with (a) and capable of ionizing in the application medium, the a/b molar ratio being between 50/50 and 10/90, in a method of reducing or preventing soil redeposition on kitchen- and tableware cleaned in an automatic dishwashing machine.
